so remove the transisitor and do the cont. diode check with the ohms setting or voltage setting on the meter?

Check it as is shown on the basic transistor testing page (link in sig line) - section for FETs.

ok will do would you like me to check both 45N10 while im pulling the one?

[Exbass17]

both 45N10 passed all 3 test the one chip was questionable cause i noticed the reading started out at 3.47 but it was still hot from the solder iron i let it cool down and it start the reading off at 5.10 close to the other 45N10

[Exbass17]

is the chips i replaced maybe not compatible with the 45n10 chips? The P chips i replaced dont seem to be getting as how as the N chips id say half as hot as those however i wouldnt think any of them should be getting hot idling the power chips both rails cold and the right output rail is bone cold as well

[Exbass17]

Also i noticed both sides a few of the diodes are getting hot the chips on the board are is that normal since the Output transistors are getting hot?

#84:
You're going to have to be very specific. This is technical and being vague is going to make is very difficult to help you.

What do you mean by 'one chip'?

3.47 what? volts, ohms..?

#85:
Don't refer to the transistors as chips.

The problem appears to be with one of the 45N10s because it had significant voltage across its source resistor while the others didn't. Did you read infinite resistance from leg 1 of the 45N10 to the other legs?

[Exbass17]

3.47 volts but the transistor was hot i could barely hold it however when it cooled down it started the voltage and stuck around 5.10 volts with the diode check i ran the 3 test how the site you showed me and everything seemed to be good with the other test they both matched up

[Perry Babin]

Was the transistor out of the board?

[Exbass17]

i took out both 45N10's that way i didnt have to remove both later plus its easier to compare them
